2). When the bobbin winding lever is positioned on the set side, it is detected by the bobbin winding lever switch 27 (Yes in step S1), and the process proceeds to the next step S3.

In step S3, whether or not the bobbin is set on the lower thread winding shaft is determined based on the detection of the bobbin set confirmation switch 28. If the bobbin is not set on the bobbin winding shaft, a screen indicating that the bobbin is not set is displayed on the display unit 11 in step S4. Here, for example, as shown in FIG.
The text "The bobbin is not set" is displayed on the screen of the display unit 11 together with a picture indicating that there is no bobbin on the lower thread winding shaft. The user can easily see from this that the bobbin must then be set.

On the other hand, if the bobbin has already been set on the bobbin winding shaft, or if the user sets the bobbin while watching the above display (Yes in step S3), the screen display on the display unit 11 will go down in step S5. The screen is switched to a screen display indicating that the thread winding is ready. Here, for example, FIG.

Press the start button. Is displayed on the screen of the display unit 11 together with a picture indicating that the bobbin is set on the bobbin winding shaft. The user can easily understand that it is sufficient to press the start / stop switch 26 here. In this state, when the start / stop switch 26 is pressed (Yes in step S6), the bobbin winding operation is started.

During the bobbin winding operation, the bobbin winding amount detector 29 detects the progress of bobbin winding one by one, and the display on the display section 11 is sequentially switched based on this. That is, in step S7, the lower thread winding amount detector 29 detects the lower thread winding amount. Although not shown, this detection
The operation is performed based on the fact that the lever of the bobbin winding amount detector 29 comes into contact with the outer periphery of the yarn wound around the bobbin, and its position is displaced as the operation proceeds. And
Until the bobbin winding amount becomes an appropriate amount (No in step S8), a screen display showing the bobbin winding amount is displayed on the display unit 11 in step S9. Here, for example, FIG.
As shown in (c), the character "The lower thread is being wound" is displayed on the screen of the display unit 11 together with a picture indicating that the lower thread is wound on the bobbin. Further, although not shown in detail, the picture showing the state in which the bobbin is wound on the bobbin is gradually thickened with the change in the bobbin winding amount detected by the bobbin winding amount detector 29. It is switched to something. The user can know the progress of the bobbin winding operation by looking at the screen display.

When the bobbin winding amount becomes an appropriate amount (Yes in step S8), the bobbin winding operation is stopped, and in the next step S10, the screen display on the display unit 11 indicates that bobbin winding has been completed and that the bobbin has been turned off. The display is switched to a display indicating how to remove. Here, for example, as shown in FIG. 4 (d), the text "The bobbin winding has been completed, move the lever to the right and remove the bobbin" is displayed on the screen of the display unit 11 together with a picture indicating the bobbin winding lever. It is displayed. The user can see this and know that the bobbin winding operation has been completed, and can easily understand the operation to be performed next. By operating the bobbin winding lever, the bobbin winding operation is completed. It is.

Next, as an example of the warning display, FIG. 5 shows a case in which the buttonhole lever 15 is erroneously operated.
Also described with reference to FIG.

The button holing lever 15 must be lowered when performing button holing and must be raised when performing other sewing operations. Now, for example, when the start / stop switch 26 is pressed in a state in which the sewing method other than the buttonhole sewing such as the linear sewing is selected by the selection switch 9, the BH lever switch 18 is turned on by the buttonhole buttoning lever 15. When it is detected that the button is lowered, the sewing operation is not started, and a display indicating that the buttonhole lever 15 is lowered is displayed on the screen of the display unit 11. here,
For example, as shown in FIG. 5 (a), the character string "Buttonhole buttoning lever is lowered" is displayed on the display unit 11 together with a picture indicating that the buttonhole buttoning lever 15 is lowered.
Will be displayed on the screen. Then, if the user performs an operation of raising the buttonhole lever 15 while looking at the screen display, it is detected that the buttonhole lever 15 has been raised by the BH lever switch 18, and then the start / stop switch 26. Is pressed, a sewing operation is started, and a predetermined sewing operation is performed. On the other hand, if the BH lever switch 18 does not detect that the buttonhole lever 15 has been raised even after a predetermined time has elapsed after the display shown in FIG. The display on the display unit 11 is switched, for example, as shown in FIG. Here, "Please raise the lever, check the type of work clamp, and press the start switch."
Is displayed on the screen of the display unit 11 together with a picture pointing to the buttonhole lever 15, so that the user can easily understand the operation to be performed next.

As described above, the display of the warning also stores a plurality of screen display data, and is switched, for example, according to the passage of time.

According to this embodiment, the execution status of each function is detected one by one by the various switches and the sensors 17 to 29, and the display unit 11 displays each function by the screen display data stored in the ROM 7. A plurality of screen displays are displayed while being appropriately switched in accordance with the execution status of the program. Therefore, unlike a conventional one in which only one message is displayed for a predetermined function such as "the bobbin is not set", the user must perform a complicated operation in multiple steps. Even if it does not, the operation to be performed next is displayed step by step, so that the user can easily understand the operation to be performed next. In particular, in the present embodiment, since both the characters and the pictures are displayed, it is possible to make the user's understanding easier.

In the above-described embodiment, the screen display when the bobbin winding function is executed and the screen display when the buttonhole hoist lever 15 is erroneously operated are described as specific examples. However, the present invention can be applied when various functions are executed. For example, the present invention can be variously modified without departing from the gist thereof.
